91 Claims.

This invention relates to machines by which fastenings may be inserted, it being herein illustrated in connection with an apparatus for attaching to shoes heels or heel-portions, as a lift of rubber or the like.

In Letters Patent of the United States No. 2,161,827, La Chapelle and Ashley, June 13, 1939, there is disclosed and claimed a machine of the character above indicated, in which the fastenings, formed in connection with each attaching operation from strings of adhesively coated, fibrous material, are subjected to the action of an inserting die having associated with it a heelhclder and a pricking and driving assembly operating through the die-passages. There is, further,,.means for feeding strings of the fasteningmaterial through predetermined distances and severing therefrom separate fastenings. These are transferred to the inserting mechanism, Where they are moistened to insure their retention in. the Work and are acted upon by different groups of drivers, as those at the breast of the heel and the remainder of the set. While the machine of the application effects the attachment of heels satisfactorily, it is an object of the present invention to further increase its efficiency and convenience.

In the attainment of the above object, my improved machine is so organized that the fastenings may readily be inserted in accordance with any one of a plurality of designs, inserting mechanisms corresponding to different designs being mounted upon such a movable carrier as a rotatable turret, simple in form and effectively supported, for presentation at an operating position at which is a Work-support. There is novel means by which the string fastening-material is supplied, and a severing or forming member is mounted upon the carrier for each inserting mechanism and by Which the fastenings are cut from the strings, they being thereafter transferred to the inserting mechanism by a member common to plural inserting mechanisms, this preferably being mounted separately from the carrier and playing a part in the cutting or forming operation. Improvements are made in the stringdelivering assembly, the pricking and driving assembly and its mounting and in the structure of the co-operating die. Means for actuating the drivers is provided whereby, as they encounter,

resistance, for example at the end of a pricking stroke or upon contact with an obstruction in the work, they not only yield, but the force which they apply decreases. Both the pricking and driving strokes of the inserting mechanism are,

(Cl. li -32) most effectively made by'a single rotation of a cam. In the movement of theturret to bring the chosen inserting mechanism into operating position at the work-support, it is indexed automatically and by means which also serves to re- 5 lease the particular driver-assembly for operation only when it is thus positioned, all the others being locked, so they may accurately be engaged by actuating mechanism common to all and which is associated with the Work-support. There is also a manually controlled lock by which the operator maintains the proper relation of the released driver-assembly to the common actuating mechanism. The string-feeding mechanism is arranged upon the machine-frame for ready removal as a unit, and to prepare for the movement of the turret or carrier when theinserting design is to be changed, there is means by which the ends of the strings advanced into the turret during the preceding operation may be retracted manually to clear the turretand then returned, ready for severing. during the succeeding operation, this manual means, at the same time, disconnecting and reconnecting the mechanism which produces the power-feed. This power-feed includes novel means for introducing lost-motion into the actuating connections to transmit from the driver-assembly. only sufficient movement to cause the correct advance of the strings. An improved fastening-cutting and -transferring mechanism of extreme simplicity is utilized, in which a compound movement is imparted to a loader-block, so it applies a considerable force slowly to shear the strings and then shifts the block rapidly to deliver the fastenings thus formed to the inserting mechanism. Alterations are made in the liquid-supplying mechanism to cause the delivery of the die-passages of an adequate but not excessive quantity of the liquid, this supplying mechanism being 40 especially adapted for use with the plural inserting mechanisms.

In the accompanying drawings, one of the several possible forms of the improved machine is illustrated, 45

Fig. 11, a vertical section through a shoe with a rubber lift which has been attached by the machine.

The frame of the machine is shown as consisting of a casing having a base-section it carrying an intermediate section l2, upon which is supported a top section M. The securing means for the sections and the openings with which they are provided to permit the passage of the elements and give access to the interior of the casing, need not particularly be described. Guided in spaced vertical ways at the front of the section 12 is a bracket .56, upon the upper horizontal portion of which is a shoe-supporting jack It with its toe-rest 2.0 and back-stop 22. These shoe-engaging elements may be shifted from an outward work-receiving position, as illustrated in Fig. 2 of the drawings, to an operating position, partially within the casing, as appears in Fig. 3. jack may be counterbalanced by tension-springs 2A, 24, joining the bracket to the casing. Pivoted at 26 upon the under side of the bracket is a block 28 provided with a vertical threaded ing receiving a screw 30 mounted to turn upon the horizontal arm of a slide 32. This slide is arranged for vertical adjustment upon a lower block 34 guided by a fork 35 depending from its lower portion. At the bottom of the block 3s a roll 35 is rotatable, it resting upon acam 38 fast upon the forward extremity of a horizontal shaft 40 journaled in the casing-section it. The shaft i0 is driven through reduction-gearing it and a single-rotation clutch 44 from a main driving shaft 46 turning in the casing parallel to the shaft 43 and which receives power from beltgearing 8. The clutch may be controlled by a rod 49 extending to the front of the machine.

To raise and lower the jack to apply preliminary or measuring pressure to the work, consisting of a jacked shoe S and a heel or heelportion H held in co-operation with inserting mechanism, which will be described lat-er, a

pinion 50, resting upon the slide 32, is fast upon the shank of the screw 3!! and has a projection 5i turning in the arm of the slide and in the top of the block 35. Meshing with the pinion is a rack 52, guided for horizontal movement upon the frame. Connections 5 3 join the rack to a treadle 56, movable at the bottom of the casingsection HI and normally elevated by a tensionspring 58. The effect of I this preliminary-pressure mechanism is as in Letters Patent of the United States No. 446,885, Pope, February 24, 1891. Final pressure to clamp the work for the pricking of fastening-receiving openings and the insertion of the fastenings is effected by the rotation of the cam 38 after the clutch M been tripped by rearward movement of the rod it. The cam in its rotation forces the block 34 up against the slide 32, which raises the block 28 and the jack. To vary the degree of clamping The Weight of the bracket and 1 rests in its initial position. This eccentric is fast upon the inner end of a short spindle $2 rotatable in the forward wail of the casing by a handle M and there locked.

To operate upon the jacked shoe and the lift to be applied, there is furnished a plurality of inserting mechanisms, each arranged in accordance with a different inserting design and equally spaced about a rotatable turret or carrier T, so anyone of the mechanisms may be brought to operating position. Save for the difference in the design, these mechanisms may be the same, so but one need be considered in detail. Depending from the casing-section it near the center of the machine is a cylindrical bearing member it (Fig. 3), having at its lower extremity an enlargement l2. About the member 79 the turret T is rotatable, it being stepped upon the portion ii. The turret has a central hub 14 about which is a ring it having at its periphery uniformly spaced vertical guide-portions 18 corresponding in number to the inserting mechanisms, in which guide-portions combined pricking and driving assemblies A may reciprocate. In the present embodiment of the invention, there are six of these guides with their assemblies. To downward extensions 89 from the ring it a circular plate 82 is secured, this turning in an Opening in vertically alined with the driver-assemblies, are

dies 8d provided with passages 92 through which the pricking stroke is made and the fastenings' are driven. They also furnish abutments against which the heels to be attached are forced. Below the dies are heel-holders 8% having arms between which is a space for the introduction of the lift to be attached (Fig. 9). The heel-holder may have turning about vertical spindles in its opposite arms, rolls 81,81, the peripheries of which may be knurled to increase their retentive effect. The space between the rolls is such that they slightly indent the rubber to hold the lift securely in place. To avoid mutilation of the lift-wall, when pressure is applied to the work and the lift rises against one of the dies 85, the rolls are permitted to shift longitudinally of their supporting spindles. Consequently, there is no relative movement between the lift and the portion of the retaining means which contacts with and might mar it. Situated upon the turretplate 82 inwardly from the dies and holders are shearing plates 88, having openings 89. Both the die-passages 92 and the shear-openings B9 are arranged in accordance with a nailing design corresponding to that of the more directly associated drivers. Under each of the shear-plates is a fiber-delivering assembly D. The lowermost portion of the turret consists of a head 1. through which water or other liquid may be supplied to moisten the fastenings. When a jacked shoe is pressed against a lift in the holder 86 of the die which is in operating position, upward dispiacement of the plate 82 is resisted by its engagement with the under surface of an abutmentyoke 90, secured to the top of the casing-section if: at Qi and extending across the front of the machine. depression at the under side of the turret-plate by screws as and dowel-pins 9 4. The passages Each of the dies 84 is secured in a 92are preferably formed in tubes 95 inserted in openings in the turret-plate and having heads 96 seated in a depression in the die-plate (Fig. 9). From the lower extremities of the tubes, which with the cooperating portions of the turret-plate may be considered as portions of the die-plate, frusto-conical projections 98 extend through corresponding openings 99 in said die-plate. These projections are adapted to enter and compress the rubber lift or heel during the operation upon it. Below the die, the heel-holder 86 is attached to the turret-plate by screws I00.

As is shown in Fig. 3 and in greater detail in Fig. 8, each driver-assembly A has a slide I02 movable in vertical ways upon a portion 18 of the turret T. From the slide is an outward projection I04, and this contains horizontal ways in which a driver-holder I08 is separably retained by a spring-actuated latch I06 entering an opening I01 in the slide. To the under side of the holder a driver-plate IIO with its backing-plate H2 is attached by screws II4 threaded upwardly into the holder. A set of drivers I I6, serving also as awls, depends from the plate H0, with their heads held against upward displacement by the plate II2. Since the breast-drivers, of which two are shown and designated by the character II1, may be required to move through a less distance 30 1 than the remainder of the set because some such obstruction as a metal shank-reinforcement may lie in their path, they are mounted upon the holder I08 to move independently. In the holder are vertical ways to receive a slide I I8, at the bot- ,tom of which the breast-driver-plate I I0 is secured by screws I20, it occupying a recess'I22 in the forward portion of the plate H0. Upon depression of the latch I06 by a hand-tool inserted in the opening II 1, the holder'may be removed from the machine, to be replaced by an assembly corresponding to a diiferent inserting design or for the replacement of broken drivers.

To give to the drivers II6 and H1 their vertical movement to prick the lift, the base which may have been attached to. the shoe, and the heel-seat of the shoe itself, and to force the fastenings from the die=passages 92 into the work,

there are guided at I28 for reciprocation in the casing-section I2 side-rods I30. These are joined at their upper extremities outside the casingsection I4 by a top-girt I32 extending across the front of the machine, while below, they are connected by a cross-girt I34 '(Fig. '1). Below the girt I34, a crosshead I36 is movable vertically in guides I38 upon the casing-section" I0, the siderods passing through this crosshead at I40. Rotatable upon the upper and lower portions of the crosshead and at opposite sides thereof are rolls I42, I42 (Fig. 2) engaged by a double cam I44 fast upon the shaft and which acts to both raise and lower the crosshead. Spaced from each other at the top of the crosshead are brackets I46, I46, between'which is trunnioned at I48 a cylindrical casing I50 containing a plunger I52 operating against a compression-spring I54 within the cylinder. Outside said casing, the plunger is joined to the center of a toggle-lever I56, I56, the'upper extremity of which is pivoted between the brackets I46, while the lower end is joined to the cross-girt I34. Through these connections,

power is yieldably transmitted from the shaft 40 to the top-girt I32. I

At the center of the top-girt, in vertical alinement with the die 84 situated in operating position, is secured a block I58 having at its under side a recess in which are spacedhorizontal ways I60, I60 curved in an are having its center at the axis of the turret T (Fig. 4). With the top-girt' edges of a curved plate I64 attached to the slideprojection I04 of each driver-assembly A by screws I66. By rotating the turret manually, as any one of the driver-assemblies with its associated die and shear-plate is brought to the front of the machine into operating relation, the driver-slide-projections I62 will enter the topgirt-ways. I60, so reciprocation of the top-girt through the connections just described will impart movement to the drivers. To insure the correct presentation of the traveling slide-projections to the normally stationary ways, each of the slides I02 is locked in the desired position at all times, except when the projections have entered the ways. This is accomplished by a plunger I10 (Fig. 3) mounted to move horizontally in each guide-portion 18 of the turret and urged inwardly by a spring I12. The plunger at its outer end is arranged to enter an opening I14 in the corresponding driver-slide, while at its inner'end, it carries a roll I16 movable along a cam-surface I18 extending about the bearing member 10. The contour of this cam-surface is such that in all positions of the turret, save when the projections I62 have entered the ways in the block I58, the plunger will be held out by. the sur face I13, so it occupies the opening I14, and the slide-projections are secured in horizontal regis- 92 ready for operation, a plunger I82 extends ver-' tically through the top-girt and is forced by a spring I84 which surrounds it into an opening I86 in the plate I64, registering with the opening I 01 in the projection I 04. To the upper extremity of the plunger is connected a'hand-lever I88 fulcrumed by a link I90 upon the top-girt (Fig. 1).

- Whenthe operator desires to change the nailing design, he may raise the plunger I82 with one hand and turn the turret with the other, each of the plungers I10 producing automatically the indexing of the turret and the release of each driver-assembly as it reaches the operating position. When the lever I88 is freed, it will lock the chosen driver-assembly in operating position. The capacity of the breast-drivers II1 to move independently of the remainder of the set, already referred to, is provided for by yieldable actuating means carried by the top-girt. Pivoted at I92 in a housing I93 secured to the front of the top-girt is a toggle-lever I94, I94, having pivoted' To hold, relativelyto' seated in the recess I22 in the plate H0. The strength of the spring is sufficient to prevent yield of the drivers II'I during their usual pricking action, but if they meet any object offering 1 undue resistance, these drivers remain stationary,

the spring compressing without injury to the parts.

With the turret located as just described, the machine may be started by movement of the rod 49 to cause the cams I44 to be rotated by the shaft 45 through 360. The contour of these cams is such that the side-rods I32 are reciprocated twice during each operating cycle. The first movement is for the purpose of pricking the lift, heel-base and heel-seat of the shoe to points at or near the plate in the last which is in the shoe. The second stroke is of less length and is for the purpose of inserting the fastenings in the pricked openings. The yieldable actuating connections for the drivers, including the spring I54, permit a full pricking movement to be made and stopped at a predetermined point. During the passage of the drivers through the work, the resistance of the spring to compression is sufficient to impart a substantially positive advance to the drivers- The stopping of the pricking movement may result from the engagement of the ends of the drivers with the last-plate or may be after travel through a less distance under the control of an element of the machine. Figs. 1 and 2 of the drawings show stop-collars 200 surrounding the side-rods and arranged to receive contact of the top-girt or a part fixed thereto. These collars may be divided for convenience in application and are of different thicknesses, so the pricking stroke may be varied in accordance with the work in hand. When the pricking movement of the drivers is stopped in either of the ways just mentioned, the toggle I56, I56, which is normally slightly broken in the direction of the spring I54, will further decrease the angle between its arms, compressing the spring and allowing continued descent of the crosshead I36 without movement of the crossgirt M4, the side-rods and the drivers. It should be noted that as the toggle-arms approach each other, the force which they apply to the spring increases, while that impressed upon the drivers decreases. Therefore, the lowering of the crosshead may continue with compression of the spring, less force being exerted which may tend to puncture the last-plate or injure portions of the machine. The effect of the toggle I94 and spring I98, in the yield of the breast-drivers III, is similar to this. In each case, the variable force is transmitted from the girt by which they are actuated. During the second or inserting stroke of the cycle, the drivers then do not meet sufficient resistance to cause compression of the spring I54, and the fastenings enter the work to definite depths. The extent of this movement and therefore the depth to which the fastenings are sunk in the lift H, may be varied by changing the position of the cross-girt I34 upon the siderods. To this end, the girt is supported between lower nuts 262 and upper nuts 2B4 threaded upon the rods. By backing off one set and turning up the other, the vertical relation of the drivers to the dies may be adjusted.

Strings of fiber 1, from which the fastenings are formed, are delivered to the shear-plates 88 of the turret T in two sets, which may be of seven each, from two feeders F, F (Fig. 1) These feeders are situated at opposite sides of the casing section I2 and are supplied with the fiber from reels 226 rotatable about spindles 228 mounted in housings 2H) carried by the casing-section I2 and closed by hinged covers 2I2. Each feeder is mounted upon a plate 2 I3 covering an opening} of the casing, so said feeder may be removed as a unit for inspection or repair.

described. As best illustrated in Figsfi and '7, 1e feeder has a pair of rolls 2I4, 2H5 provided with registering peripheral grooves 2H3 through which the strings of fastening-material pass and which may be toothed to better engage ,said strings. The shaft 2I9 of the roll 2 I4 is journaled in a supporting frame 22!] secured to the cover 2I3, while the shaft 22I of the roll 2I6 is journaled in a swinging frame 222, hinged at 224; The swinging frame is acted to the frame 225. upon by a spring 226 surrounding a rod 228 pivoted at 23-5 to the fixed frame. of the spring abuts against a nut 232 threaded upon the rod. By adjusting this nut, there may be varied the force with which the rolls bite the strings to insure advance. At 234, the rolls are geared to rotate together. The driving force is a vertically reciprocatory rack 245 guided in the frame 220 and receiving movement through a,

link 242 pivoted to it and to a second link 244,

which, in turn, is pivoted to a collar 246 secured" to the adjacent side-rod I30. Upon the sleeve,

the shaft. To the outer extremity of the sleeve 254, outside the plate EH3, a hand-wheel 255 is secured. A long spline 25am the sleeve 254 receives a feather 25! in the shaft. An expansionspring 258, interposed between theinner face of the plate 2I3 and the flange of. the sleeve 254,

urges said sleeve and hand-wheel in, so the projection 253 occupies one of the openings 252. In this relation, intermittent rotation imparted by reciprocation of the rack 240 through the pawls 248 to the ratchet-wheel 25B is transmitted through the sleeve 25I, the projection 253, the sleeve 254 and the feather 251 to the shaft 2I9. This causes the rotation of the rolls El iv and 2H5, and the feeding up of the fiber strings step by step from the reels 256. If the operator wishes to withdraw or advance the strings manually, in connection with rotation of the turret to change the inserting design, the sleeve 254 is pulled out by the hand-Wheel, until the sleeve-projection When the machine is at rest, there is a space.

between the lower ends of the drivers and the upper face of the turret-plate 82, into which space The feeders may: be identical in construction, so but one will be'.

The outer extremity applied to the the shaft 219 of roll 2M through f I a sleeve 2% surrounding the shaft and having fast upon it a gear 238. With this gear meshes may be moved the transferring means which delivers fastenings from the shear-plate-op'enings 89 to the die-passages I32. In the travel of the drivers through this space, the descent of a siderod causes the link 244 to swing the link 242 from contact with a surface 260 upon the rack 240 into engagement with a surface 262 thereon. During this movement, whichis indicauses downward travel of the rack corresponding to a distance equal to the difference between the pricking and fastening-inserting strokes of the drivers and therefore to the length of the fastenings themselves. This may be communicated through the connections previously indicated to'the rolls 2|4, M6, the resulting rotation of which rolls will draw oif from the reels we measured lengths of the fiber strings. When the extent of travel of the drivers is Varied by their contact with the last-plate or because of adjust ment of the stop-collars 200, the length of the fiber fed is correspondingly altered. Reverse rotation of the rolls during the idleo-scillation-of the pawls may be prevented by detents 264, 264 pivoted upon the frame 220 and urged against the periphery of the ratchet-wheel 25G by springactuated plungers 265. Backlash in the rolls prevented by a friction-segment 258 movable upon the frame 222 and forced against the roll 2&6 by a spring 210, I

From the feeders, the strings pass through tubes 212, which are held at their upper ends in a terminal-bar 213 secured to a bracket 2'64 attached to one side of the casing-section l2 (Fig. 1). For each of the shear-plates 88 there is depending from the turretplate 32 a support 215 forming a part of one of theflber-deliveryassemblies D and to which is secured a terminalbar 216. From the bar, rise tubes 2'59 (Figs. 3

and 9) terminating above in a plate 2893 in which v are arranged tube-receiving openings in registration with the openings 89 of the shear-plate, this relation being maintained by dowel-pins 2&2.

'Thus, the strings, as they are measured off by the feeders for each inserting operation, are carried through the shear-plate to the amount necessary for the fastenings, ready to be severed and transferred to the die-passages 52 in position for driving. This transfer is effected by a loa,der block 290 (Figs. 3 and 5) cylindrical in form and arranged to turn in a recess at the outer end of a slide 292 reciprocable in horizontal ways formed at the bottom of the portion 12 of the bearing member for the turret. Through the loader-block are passages 294 corresponding to a plurality of inserting designs to be employed. In the present instance, three sets of these passages areillustrated for a like number of driverassemblies and dies. If the other three designs carried by the turret T are to be used, another multiple block may be substituted. The block has a rearwardly extending arm 296, the end of which has an opening to receive a crank-pin 298 rising from a horizontal disk act fast upon the upper end of a shaft 30! journaled in the casing-bracket 214. The shaft is rotated to produce through the crank-pin the successive rotation of the loader-block in its slide and the reciprocation of said slide with the block. Power is supplied to the shaft 3! by a cam 392 (Fig. 2)

fixed to the shaft 40. With the cam contacts a roll .304 rotatable upon a double bell-cranklever 306 fulcrumed upon the casing-section It. The roll is held against the cam by an expansionspring 308 surrounding a rod 35!] joined to a depending arm of the bell-crank. The other arm carrying the roll 304 is connected by a double link 312 to an eccentric 3l4 (Fig. 3) mounted for angular adjustment in the lower extremity of a rack 316 guided to reciprocate vertically upon the back of the bracket 214; The eccentric may be turned to vary' the normal relation between the link and rack by a short rod- 3H3 acting through worm-gearing 32B. Thereby registration may be established betweenthe loader-block-passages and one of the sets of openings with which there is to be registration at its opposite extremes of travel. The rack 3|6 has helical teeth and through similar gears 324,324 turns the shaft 305. When the machine stops, the cam 302 and its connections locate the loader-block over the shear-plate 88 of the turret, which is then in operating position, the crank-pin 298 being in the dash-line position shown inFig. 5 and the plate-openings and block-passages being in registration. The block preferably carries at its under side a perforated shear-plate 326 cooperatingwith the plate 88, the openings in the plate 32% and an upper plate 328 upon the block being held alined with the block-openings by dowel-pins 330. The fastening-material is delivered by the feeders F, F, through the openings in the shear-plate 88 into the loader-block-passages 2G4. When the crank-pin revolves to the full-line position in Fig. 5, as it crosses the center removed from the inserting mechanism, it acts first to rotate the loader-block to such an extent that the openings in the plate 326 pass out of alinement with the openings of the shear-plate 38, cutting off measured lengths of the strings. Itshould be observed that during this severing action, the pin is passing over a center in its revolution across the path of the slide, exerting its full force to divide the material without appreciable movement of translation of the loaderblock. The continued revolution of the crankpin through nearly 180 moves the slide 292 rap idly forward and turns the block but slightly upon the slide as it is advanced bodily, until, at the opposite center, the loader-block-passages pass into registration with the die-passages 92.

- Here. they are retained long enoughv for the fastenings to be driven through the die into the work by the descent of the drivers I I6, H1, after which continued movement of translation and rotation of the block restores it quickly to its receiving position, with the crank-pin again at thepoint shown in dash-lines. When the loaderblock is in its forward delivering position, a rear. ward extension 33| from the plate 326 covers the shear-plate-openings. This guards against protrusion of the strings through said openings at all times, 'save when the block-passages are in position ready to receive them. By adjusting the eccentric 3| 4, the vertical relation of the rack 3E6 will be altered to produce normal regis-v tration of the block-passages 294 with the shearplate-op'enings 89.

Moistening of the severed fiber pegs to increase their holding power in the work may be effected by water or other liquid circulated by a pump 336 (Fig. 2) mounted in the bottom. of the casingsection IE! and actuated by a cam-segment 337 secured to the shaft 40, this cam contacting with.

a roll 338 rotatable upon the upwardly extending piston-rod 339 of the pump. The water is delivered to the pump by a pipe 335 from a tank 34 I, mounted at one side of the casing-section l2 (Fig. l), and from the pump through a'pipe 340 to a vertical passage 342 in the bracket 214 (Fig. 3). The passage 342 leads through the upper horizontal surface of the bracket, which is in close contact with the lower surface of the turret-head t (Fig. 10). Aspring-pressed gasket 344 may be situated in a recess about the exit of the passage 352 to prevent leakage between the surfaces. In the surface of the turret opposite the passage 342 is a series of passages 346, from each of which a pipe 348 radiates to a passage in the turret-plate 82, through which it delivers to a groove 35!) in the upper face of the associated die-plate 84 (Fig. 9). In this groove 350, surrounded by a strip 35! of felt or other absorbent material, lie the heads 93 of the dietubes 95, through the sides of which heads are horizontal slots 352. Upon the upward pressure-stroke of the pump 336, water is supplied .to the groove 35!], saturating the felt. This occurs While the drivers are rising from their pricking stroke, and while their ends close the tube-slots 352, avoiding undue flow into the passages 92. When the drivers are elevated after they have pricked the work, there is sufficient free water in the groove to flow through the slots 352 into the passages 92 and be there held by the li t H, which closes the lower ends of the passages. A segmental groove 35 i in the upper surface of the head 15 registers with the passages 345 but terminates at its ends short of the inlet-pipe 342. A vertical passage 355 in the bracket 2M from the groove 354 is connected by a pipe 356 to the tank 34!, thus allowing the water from the grooves 353 of all the dies other than that to which the inlet passage 342 is joined, to drain back to the tank. Upon the downward suctionstroke of the pump, which takes place immediately after the pressure-stroke, the excess of water which has been delivered to the groove 3%, and that which may surround the rising drivers, will be withdrawn through the pipe 340, leaving only that in the passages 92 below the slots 352. This prevents drip from the passages, in the loader-block 2961, when this returns to its receiving position. As the drivers force the fastenings through the die into the work, said fastenings are moistened by the retained water to swell and render them adhesive, while the entrance into the rubber of the lift is made easier by the lubricating effect.

Let there be assumed a use of the machine when it is desired to change the nailing design. From the preceding operation, the strings I of fiber will be extending into the shear-plate 88, passing from the stationary bracket 214 into the revolving turret-bar 275. Therefore, the strings must first be withdrawn downwardly from the bar. The operator effects this by pulling out the hand-wheel 255, so the feed-roll 284 is disconnected from the power mechanism, and by turning the roll clockwise, as viewed in Fig. 7. By depressing the lever I88, the operator removes the locking plunger 182 from the depression H86 of the turret T and rotates said turret until the inserting mechanism arranged in accordance with a chosen design is at the front of the machine. As the turret is turned, the roll I16 of the driver-assembly which has been in the depression I80 in the turret-bearing, leaves this, and when the roll of the assembly which is to be employed reaches the depression, itis allowed to remain in and index the turret, simultaneously freeing the driver-slide H32. After this, rotation of the feed-roll 2H! in an anticlockwise direction will restore the strings to their positions in the shear-plate-passages with their ends against the block-plate 32B, ready to be fed by the machine. The Work to be done may be the attachment to a shoe S, having already secured upon it a base B, a lift H, consisting of rubber a molded about a cord b of wood. With the jack l8 drawn out upon its bracket it, the operator inserts the lift H in the holder 86, jacks the shoe and moves it back beneath the lift, gaging the position by the backstop 22 and the toe-rest 2G. Lowering the treadle 56, he rotates the screw 30 to raise the block 28 with the jack, until the surface of the base B contacts with the opposed face of the lift, and trips the clutch M by actuation of the rod 49. This initiates a power-cycle of the machine. As the shaft 40 rotates, the cam 38 lifts the slide 1% to apply clamping pressure to the work, the upward displacing force upon the turret being resisted by its contact with the yoke 99. This applicationof final pressure is succeeded by the descent of the top-girt I32 under the influenceof the cams M4. The drivers H6 and H7, now acting as awls, are carried down throughthe diepassages 9?. for their full stroke, the extent of which is determined by the yield of the spring l54 when the ends of the drivers strike the plate of the last in the shoe or when advance is stopped by the contact of the top-girt with the side-rodcollars 200. In this movement, the breastdrivers ii! yield against the spring E88, if they find in their path an object which cannot be penetrated without danger of breakage. While.

the drivers are making their first, pricking stroke,-

the connections to the side-rod-collars 2% rotate the feed-rolls 2M, 2H5 to advance the correct lengths of fiber strings f for theformation' of the fastenings to be inserted in the pricked openings, the ends of the strings rising through the shear-plate-openings 89 of the turret and the registering openings in the shear-plate 3'25 of the loader-block into the loader-block-passages 2%. This accomplished, the cam 302, revolving the crank-pin 298, first rotates the loader-block, be-

fore the descent of the drivers in their second,-

inserting stroke, to divide the strings in the meeting plane of the shear-plates into discrete fastenings g and thereafter carries the block forward with the slide 292 to aline the blo-ck-pas sages with the die-passages 92. After the drivers have pricked the work and before the fasteninginsertingstroke, the pump 336 is actuated by the cam 331 to force water into the groove 350 into the die 84 and the felt 35I therein, from whence,

it flows through the slots 352 into the lower portions of the die-passages 92 just above the liftentering projections 98. As the drivers make their inserting stroke, actuated by the second period of rotation of the cams I44, the fastenings g in the loader-block-passages are driven from these through the die-passages into the work, as

is shown in Fig. 11, being moistened by the water in the lower portions of the passages 92 to increase their hold upon the work. Preferably, heads h, which are formed by the upsetting of the fastenings under the driver-pressure, lie in the lift H at the outer face of the core b. During this driving movement of the side-rods E30, the feeding mechanisms F are ineffective, because of the idle movement of the links 242 between the rack-surfaces 260 and 262. The depth of insertion of the fastenings may be determined by the adjustment of the cross-girt I34 upon the siderods, and the extent of the pricking stroke of the drivers and length of the severed fastenings by change of the stop-collars 280. In the initial passages 92 in which the water has been held, so

drawing it back that little .or no. drip will occur when the shoe with its attached lift is separated from the tube-ends 98. As the shaft completes its rotation, the cam 38 releases the block 34, so the jack is lowered, and upon removal of the work, the machine is ready for another operation.
